براغي رأس سداسي 7/8-9 × 3 بوصة | فولاذ درجة 8 مطلي بالزنك | ملولبة جزئيًا (60/عبوة)

Installed these on a jig that sees heavy vibration and the grade 8 steel threads held tight without any stripping. The partially threaded design made alignment quicker too.

Used these on a heavy-duty jig I’m building, and the partially threaded design grabbed perfectly without slipping. The zinc plating feels solid and hasn’t shown any rust after a few weeks in a damp shop.

Finally, a bold fastener that handles high-torque jobs without stripping—the partially threaded shank gave me just the right grip on my press frame. These Grade 8 bolts came well-packed and the zinc plating looks clean, no rust worries.
